Haemophilia A is a genetic coagulation disorder requiring prophylactic Factor VIII (FVIII) treatment to prevent joint damage and enhance quality of life. The introduction of extended half-life (EHL) FVIII products represents a major advancement, addressing patient needs for reduced infusion frequency, improved efficacy, and enhanced safety.
This single-centre observational study examined the real-world use of FVIII products among 124 male patients treated at the Haemophilia Centre of Padua from January 2018 to December 2023. Data on patient characteristics, treatment regimens, and pharmacokinetic profiles were analyzed.
Among the FVIII products used, Advate®, Elocta®, and Jivi® showed median half-lives of 11.25 [10.75-12.25], 16.50 [13.75-17.75], and 15.38 [13.38-18.63] hours, respectively. Esperoct® exhibited the longest half-life at 19.75 [16.00-24.50] hours, enabling reduced infusion frequency. EHL products showed significantly lower weekly infusion rates compared to standard half-life (SHL) products (1.4 [1.0-2.0] vs. 2.0 [2.0-3.0], p < 0.001), with comparable bleeding control among the different FVIII-EHL.
EHL FVIII products offer significant clinical benefits, reducing the burden of frequent infusions and improving adherence while maintaining effective bleeding control. Despite these advancements, comprehensive evaluations of cost, safety, and long-term outcomes are essential to optimize their integration into haemophilia care.
甲型血友病是一种遗传性凝血障碍疾病,需要预防性使用凝血因子 VIII(FVIII)进行治疗,以预防关节损伤并提高生活质量。延长半衰期(EHL)FVIII 产品的推出是一项重大进展,满足了患者减少输注频率、提高疗效和增强安全性的需求。
这项单中心观察性研究调查了 2018 年 1 月至 2023 年 12 月在帕多瓦血友病中心接受治疗的 124 名男性患者对 FVIII 产品的实际使用情况。分析了患者特征、治疗方案和药代动力学概况的数据。
在所使用的 FVIII 产品中,Advate®、Elocta® 和 Jivi® 的中位半衰期分别为 11.25 [10.75 - 12.25]、16.50 [13.75 - 17.75] 和 15.38 [13.38 - 18.63] 小时。Esperoct® 的半衰期最长,为 19.75 [16.00 - 24.50] 小时,能够降低输注频率。与标准半衰期(SHL)产品相比,EHL 产品的每周输注率显著更低(1.4 [1.0 - 2.0] 对 2.0 [2.0 - 3.0],p < 0.001),不同 FVIII - EHL 产品在出血控制方面相当。
EHL FVIII 产品具有显著的临床益处,减少了频繁输注的负担,提高了依从性,同时维持了有效的出血控制。尽管有这些进展,但对成本、安全性和长期结果进行全面评估对于优化其在血友病治疗中的应用至关重要。
